4-22. A distillation column is used to separate a mixture of methanol, ethanol, and isopropyl alcohol. The feed stream, with a mass flow rate of 300 kg/hr, has the following composition: Component methanol Species mass density 3 395.5 kg/m 3 197.3 kg/m ethanol 13 196.5 kg/m isopropyl alcohol Separation of this mixture of alcohol takes place according to the following specifications: (a) 90% of the methanol in the feed leaves with the distillate stream (b) 5% of the ethanol in the feed leaves with the distillate stream (c) 3% of the isopropyl alcohol in the feed leaves with the distillate stream. Assuming that the volumes of the components are additive, compute the concentration and volumetric flow rates of the distillate and bottom streams

What are component-coupling effects in mass-transfer-rate equations?

1.Briefly introduce microfiltration(MF)and reverse osmosis(RO),and what are the majordifferences between microfiltration and reverse osmosis?

a) Why flotation process is necessary in many cases for ore processing in extractive metallurgy? Explain the difference between the bulk flotation and selective flotation using the related flow-sheets basic steps of flotation operation
